oil shale extraction
Shale oil extraction - Wikipedia
Shale oil extraction is an industrial process for unconventional oil production. This process converts kerogen in oil shale into shale oil by pyrolysis, hydrogenation, or thermal dissolution. The resultant shale oil is used as fuel oil or upgraded to meet refinery feedstock specifications by adding hydrogen and removing sulfur and nitrogen impurities. Shale oil extraction is usually performed above ground (ex situ processing) by mining the oil shale and t

oil shale National Geographic Society
Mar 04, 2013 Extracting and processing shale oil is an expensive and difficult process. Coal, petroleum, and natural gas are less expensive to extract. Australia, Brazil, Switzerland, Sweden, Spain, and South Africa began mining oil shale in the 19th and 20th centuries, but they all stopped production by the 1960s. The U.S. ceased production in the early 1980s.

Oil Shale Extraction HowStuffWorks
Apr 21, 2008 The process of extracting liquid crude oil from the ground is comparatively simple to extracting oil shale. Pressure from gases trapped in the chamber where oil is present force the crude oil to the surface. After this pressure is alleviated, the more difficult secondary and tertiary phases of oil

Shale Oil: Definition, Production, Fracking, Pros, Cons
Dec 30, 2020 Shale oil extraction methods are more flexible than traditional oil well drilling. The initial drilling only accounts for 40% of the total cost. Extracting the oil costs roughly $1 million for each well. That made shale oil extraction profitable when oil reached $100 a barrel.

Oil Shale Processing - an overview ScienceDirect Topics
Mar 15, 2011 Shale oil processing is defined as an industrial process to which raw shale oil is subjected to extract oil from it—basically a process to produce unconventional oil [1]. Because shale oil exists as solid sedimentary rocks, its extraction is more complex than extraction of conventional oil [1] .

Oil shale - Wikipedia
Most exploitation of oil shale involves mining followed by shipping elsewhere, after which the shale is burned directly to generate electricity or undertakes further processing. The most common methods of mining involve open-pit mining and strip mining. These procedures remove most of the overlying material to expose the deposits of oil shale and become practical when the deposits occur near the surface. Underground mining of oil shale, which removes less of the overlying material, employs the room-and-pi

Jan 01, 2021 The extraction experiments were carried out in 0.5 L stainless steel autoclaves. For each experiment, the autoclave was loaded with approximately 80 g oil shale and 250 mL distilled water or FeCl 2 solution. After the autoclave was sealed, high pressure nitrogen was used thrice for purging the air in the headspace of the autoclave and was then released to keep the system at atmospheric pressure.
